عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: أَتَتْ فَاطِمَةُ بِنْتُ أَبِي حُبَيْشٍ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَتْ: إِنِّي أُسْتَحِيضْتُ، فَقَالَ: ((دَعِي الصَّلَاةَ أَيَّامَ حَيْضَتِكِ ثُمَّ اغْتَسِلِي وَتَوَضَّئِي عِنْدَ كُلِّ صَلَاةٍ وَإِنْ قَطَرَ عَلَى الْحَصِيرِ))
It is narrated from Sayyida Aisha (RA), she says that Sayyida Fatima bint Abi Hubaysh (RA) came to the Holy Prophet (peace and blessings be upon him) and said: I experience the blood of Istihada (non-menstrual bleeding)? The Holy Prophet (peace and blessings be upon him) said: Then during your days of menstruation, leave the prayer, then perform ghusl (ritual bath) and offer prayer, and perform wudu (ablution) for every prayer, even if drops of that blood continue to fall on the mat.
